General Relativity predicted existence of Black holes. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. But The Chandrasekhar limit is the maximum mass of a stable white dwarf star. White dwarfs with masses greater than the limit undergo further gravitational collapse, evolving into a different type of stellar remnant, such as a neutron star or black hole. This limit was initially ignored by the community of scientists because such a limit would logically require the existence of black holes, which were considered a scientific impossibility at the time. So who should we give credit for being able to consider the possibility of Black Hole Einstein or Chandrasekhar or John Michell in 1783 (Much before Einstein or Chandrasekhar)? Since Michell suggested that if there were an object with 500 times the radius of the sun, but with the sun’s average density, then its escape velocity would be faster than the speed of light.
